} MEAT oHoPrER 2 24 I Application i- February 'aa'iezs, s ia1nae4a45a.

- My'invention relates to certain improvementsin the cutterheads of choppers for meat and like substances.

. One object of my invention is' to provide w means for holding the meat from rotating in the chopper while it is being forced into .the perforated'conical cutting head bythe feed screw. v I Another object of the inventionis to insure the proper seating, of the conical cutter in the perforated cutting head, and to hold the outer end of the feed screw in proper alignment with the barrel of the chopper.

In the accompanying drawings 1 Fig.1 is a sectionalplan viewof the barrel of a meat chopper, with the'perforated conicalcutting head and clamping screw; 7

Fig. 2 is a 'rear end view of theconical cutting head; and I I j Fig. 3 is a sectional view of a portion of the feed screw and the conical cutter.

In the present instance,;1 is the barrelof.

aower meat cho )er "havin a series of longitudinal internalfribs 2, which prevent the meat rotating withthe screw, which is shown by dottedlines 3 in Fig. 1, 4 is the conical cuttinghead whichhas anumber of perforations 5 of any suitable size and a flange 6 formed' on the rear end of the cutting edge,

, which rests in airecess' 7 in the outer end of the barrel 1. i

' J 8 is 'aclamping ring 'whichbearsfupon the flange 6 of the'cutting head and has a screw- 12 in'the cutting head, toprevent the head turningin the barrel.

. Theginner surface of the cutting portion offthe cutting head is smooth, the projection.

of the meat into the perforations being def pended upon to hold themeat' from turning o as itis forced into the cutting head'and the projection severed, and in orderto prevent the meat turning with thescrewfa's it passes from the control "of' theribs of the barrel,

' short ribs 13 are formed at'the rear end of the cutting head, which preferably align with the ribs of the barrelyand these ribs extend preferably to theline of the first series i the ball 18 finds its bearing.

perforations, fsofthatthe ineat'isfpositively i from turningwhile being conveyedby; the feed screw from the hopper, whichis at the rear end of the ba'rreland'not shown theperforations {in the cutting head. a f" :ilThe machines towhich {thisinvention at theforward end of the machine will turn with Wa PI V fingfurtheri'fedi of the meet, and, n eq t y, ei cuaingt operationwill cease, but by my invention the meat is held from turning untillit is severed by the cutter at the end of the feed screw In the present instance on the end of the feed screw 14 is a rectangular boss 15 which fits a like cavity 16 in the conical cutter 17.

The cavity is of suificient size to allow the conical cutter tohave a certain amount of play, so that it can seat itself properly in the conical perforated cutting head. On the end of the boss is a projection 18 in the form of a section of a ball which, in the present instance, is made separate from the feed screw,

In the conical cutter isa socket, in which This socket is located about midway of the length of the conical cutter, so as to allow the cutter to properly seat itself in the conical perforated head. The ball-and-socket being on the'longitudinalline ofthe feed screw, it forms a center'bearing for the outer end of the feed l screw, keeping it'in proper alignment.

I claim:

1. The combination in a cutter for meat and like substances, of a barrel; a feed screw mounted in the barrel; a conicalperforated cutting head secured to the barrel; a conical cutter adapted to the perforated conical head; a ball-and-socket joint'between the out ter and the feed screw located substantially positivelyjl eldQnot' onlyby the'ribs of the barrel but by the continuation's of the ribs i 60. on the cutt nghead, that port on ofthe meat having a threaded stem 19 which is adapted to a threaded opening 20 in the boss. 3' 1 midway between the two ends of the cutter; i and a loose driving connection between the. screw andthecutter, thGbiLllfltHClfiOkQl; be-

- ing on the longitudinal line of the feed screw and acting to retain the outer-bend of the screw in alignment. V

2. The combination in a cutter for meat and like substances,0f a barrel; a conical per forated cutting head secured to the barrel; a :feed screw mounted in the barrel, said feed screw having arectangular boss; aball seg- I ment projecting: from the end of the boss; and a'cutter having a socket for the ball segment 7 and having a'loose fit on the boss to. allow the cutter to seat itself in the perforated cutting head.

3. The combination in a cutter for'meats' and like substances, ofabarrel having ribs therein which vprevent the meat turning within the barrel 5' a perforated conical cutting head; means for securing the cutting head to the end of the barrel, said cutting head hav- 'ing pe-rforations into which the meat is forced andhaving'a 'series'of short ribs at its end aligningwi'th the ribs of the barrel and extendingjto the first series of perforations in v Said'head'; a feed'screw; anda separateconi cal cutter mounted on the end of the feed s'qlw and arranged, to turn therewith, the at the inner end of the c'onicalcutting -head. preventing the meat turning after it leaves the ribs of the barrel and prior to its $9 entering the perforationsin the cutting head,
